Finding the equation of a line using point slope form given a point and slope

The video tutorial explains how to find the equation of a line given a slope of four and a point (6, 9). It covers two forms of line equations: slope-intercept and point-slope. The instructor demonstrates using the point-slope form to derive the equation, emphasizing the flexibility of choosing which point to use. The process involves substituting the slope and point into the formula, applying the distributive property, and simplifying to find the final equation.
